Fig. 6: Recovery of broadband spectra with 4 filter units.
From: Miniaturized on-chip spectrometer enabled by electrochromic modulation
The reconstructed spectra of three different broadband spectra are shown in (a), (b), and (c), respectively. The reconstructed spectra under different detection modes (m = 1, 2, 3) are presented in different columns. The reference spectra measured by a commercial spectrometer are plotted in dotted lines. The bandpass filters are placed between the white light source and the ECOS
